Watched this film on NETFLIX (Little Dieter needs to fly). It's about a German immigrant Dieter Dengler who came to America to join the US Military to become a Pilot. He was the first US Navy Pilot to escape in the Vietnam war. A good movie worth watching.
Man he really wanted to be a Pilot bad read this in one of the links I posted when he went through Navy Pilots training.
Dieter would do whatever it took to become a pilot. In his inaugural flight at primary flight training, for example, the instructor told Dieter that if he became airsick and vomited in the cockpit that he would receive a "down" on his record. Students were only allowed three downs then they would wash out of flight training. The instructor of course, took the plane through spins and loops causing Dieter to become dizzy and disoriented. Knowing he was about to vomit and not wanting to receive a "down" Dieter took off his boot, threw up into it and put it back on. At the end of the flight the instructor checked the cockpit and could smell the vomit, but couldn’t find any evidence of it. He didn’t get a "down".
